Would it be possible for repeated switch cases to throw a warning? I just spent at least an hour debugging code because I had
switch(N)

    if(1)
        src2 = BYTE_ONE(src2) + BYTE_ONE(Int1)
        src1 = BYTE_ONE(src1)                  + BUFFER(src2)

    if(2)
        src3 = BYTE_ONE(src3) + BYTE_ONE(Int2)
        src2 = BYTE_ONE(src2) + BYTE_ONE(Int1) + BUFFER(src3)
        src1 = BYTE_ONE(src1)                  + BUFFER(src2)

    if(2) // Repeated here, instead of if(3).
        src4 = BYTE_ONE(src4) + BYTE_ONE(Int3)
        src3 = BYTE_ONE(src3) + BYTE_ONE(Int2) + BUFFER(src4)
        src2 = BYTE_ONE(src2) + BYTE_ONE(Int1) + BUFFER(src3)
        src1 = BYTE_ONE(src1)                  + BUFFER(src2)

There is no scenario—given DM's switch statement behavior—where you would actually want this (or at least no scenario I can conceive of).

Hmm. Potentially difficult but not impossible. I'll have to study the code that compiles the switch.
